Proposta de melhoria de produtividade em uma indústria metalúrgica utilizando ferramentas do lean manufacturing

Abstract

This work analyzes the application of Lean Manufacturing tools in a metallurgical industry with the aim of improving productivity. The contextualization of the problem highlights the challenges faced by traditional companies, such as low productivity and inefficient management. The methodology used included the development of the Value Stream Map and the application of tools such as time analysis and line balancing on the grader production line. The study identified problems in the production system and proposed improvements, including the creation of a dedicated welding cell and the reorganization of workstations. As a result of the improvements, there was a 78-minute reduction in value-added time and a 17% decrease in the number of employees required in the production process. This resulted in a 73% increase in productivity. This study demonstrates the effectiveness of using lean manufacturing principles and the positive impact on the optimization of the production process.
